GandalfTheWhite Posted June 28, 2009 Share Posted June 28, 2009 Hi, when i start defraggler for my small drives a single file with the size of about 10MiB going to be "defraged" within no time. The Size of the volume is 50GiG. The same fragmented File on a 1TB Disk needed about 5 Sekonds to be defraged - sounds not much - but the whole defragment process takes about 24h on the 1TB Disk. Well, after the first run of defraggle i tried to just defragment some single files - but the time for defragmenting 100 files of 10 mb is about 10 mins. The measured drive speed for both drives are about 60MB/s (SATA) on a Q9450 System with 4Gig of Ram/Win XP64. When i defag some single files on the large volume defraggler needs a long time before an action (read/write) is indicated - what i mean is a few seconds nothing happened, then a short "flicker" of read/write activity and then a long pause before the new "shown" acitivity. Also defraggler is only using 25% (1 core) for the defrag process - on very short time periods there is something about 35%. Would be nice if defraggler could use more than one core for a longer time period -> maybe then it would be faster on large volumes. The Drives are both formated with NTFS. Gandalf PS As you could read here the problem seems to be the large drive not NTFS/FAT32. PPS My System: Q9450, 4 GiB Ram, WinXP64, 1TiB Disk, 250GiB Disk Link to comment Share on other sites More sharing options...
MacGyverDB Posted June 28, 2009 Share Posted June 28, 2009 I have the same problem. 320 Gig HD, USB 2.0 hookup. Took 3 hours to go 5%. This is right after using a different company's defrag, which was completed within 20 minutes on the same drive. I THOUGHT this was going to be a good program considering how well CCleaner works.

damnation Posted June 29, 2009 Share Posted June 29, 2009 I'm having a seemingly similar issue on a ~500GB SATA 7200RPM drive. It has been running all night and still only 42% done on Vista 32 bit home premium, running AMD Quad Core Phenom 9950 4GIG OCZ Ram. Status 21 Fragmented Files (26.7GB) 164 Total Fragments 21% Fragmentation Properties Used Space : 135,349,288,960 bytes (126.1 GB) Free Space : 364,756,451,328 bytes (339.7 GB) Capacity : 500,105,740,288 bytes (465.8 GB) On my old 250 GB IDE drive under XP Defraggler used to fly. Please let me know if you require any further details to help fix this issue. Cheers! Link to comment Share on other sites More sharing options...
GandalfTheWhite Posted July 5, 2009 Author Share Posted July 5, 2009 Hi, I've now the proof that the size of the drive is the fact that matters... - Defraggler runs extremly slow on my 1TB Drive - createt a 10GB File/Virtual Hard Disk on this Drive (the file itself is not fragmented!) - the virtual HardDisk contains 10GB of fragmented Data (not the file itslef is fragmented!!) - defragmentation of the virtual harddisk is really fast 100 MB File in less than 3 seconds but the same file on the 1 TB Drive (note: they are the same phys. drive) needs about 2 to 3 min!

GandalfTheWhite Posted July 5, 2009 Author Share Posted July 5, 2009 Hi, started defraggler in debug mode for 1 file (10MB) - maybe you could have a look.
